Specification ot Letters Patent.

Patented May 31, 1910.

Application filed August 12, 1905. Serial No. 273,914.

To all whom fitmay macero: l

Be it known -that'I, GUsTAF JOHNSON, a citizen of the'United States,anda resident of Pigeon Cove, in the county of Essex and State ofMassachusetts, have invented a new and Improved Votin Machine, of whichthe followin is a ful clear, and' exact description, re erence beingmade therein to the accompanying drawings.

This invention relates to voting machines wherein errors-in voting canbe corrected by the voter without prejudicing his vote, at any timebefore he leaves the v oting booth, and whereby group voting, in itswidest scope, is made possible wit-hout chance of fraud o1l errors, andis an improvement upon my voting machine' covered by Letters-Pat-- entNo. 737,412, and dated August 25, 1903.

In connection with the above noted improvements, I have provided new andimproved mechanism for the entrance and exit levers, which is- Afullydescribed, but not claimed herein, as itv formsthe subject matter ofanother application of even date yherewith. I also provide means forautomatically-registering the total number of voters using the machine,thereby doing away with vthe uncertainty caused by some votersvoluntarily negleetingto avail themselves of their full privilege. Forillustration, some voters may not care Ato cast a ballot for ma or,others will pass over the clerk, etc.,

an consequently it would be difficult to determine .from the dials hon7many persons had voted, were it not for this improvement. There areother minor improvements which will appear in thc following detaileddescription, and which are fully illustrated in the accompanyingdrawings, which form art of this specification, and in which simiarreference characters are used for the same parts throughout.

Figure 1 is a general perspective view of my improved voting machine; Fi2 is a partial rear elevation of same, wlth parts removed here andthere, for greater clearness Fig. 3 is a vertical section correspondingto line 3--3 of Fig. 2; Fig. 4 is a partial )lan section 'correspondingto `line 4% of "i r. 2; Fig. 5 is an enlarged sectional detai of aportion of Fig. 3; Fig. 6 is an cnlarged view of a.` portionofthemachine as seen in Fig. 2; Fig. 7 is .an enlarged rear view of themechanism around one voting i spindle, as seen in Fig.'2; Fi 8 is apartial View of the front or voting ace of the madetail corresponding toline 9-9 of Fig. 5; FigsvlO and 11 are`sectional details showing themechanism for the entrance and e'xit levers, and correspondrespectivelyto lines 10-10 and 11-11 'of Fig. 2; Fig. 12 is a partialsectional plan view corresponding to line 12-12 of 3; Fig. 13 is aperspective detail of -tportions of the votin spindle ,and key; Fig. 14is a rear view o one of my registering devices with the counting dialsremoved; Fig. 15 is a section on line 15-15 of Fig. 14; Fig. 1G is asection on line 16-16 ot Fig. 14; Fig. 17 is a detail of the countingdal for number of voters.

In the drawings, referring to Fig. 1, it a willlbe noticed that thefirst vertical column to the left is reserved for straight partyvoting,except the lowest space, which is blank. The lowest horizontal row isforth@ purpose of voting for candidates whose names are not mounted inthe spaces C. The spindles controlling this row of spaces operate rollsof paper within box B, whereonthe desired this pur ose is the same asshownin Letters- Patent l\'o. 737,412, and claimed thereunder, and willnot befurther described in this application, reference being hereinvmade to said patent. The spaces C are covered with a transparent shield,preferably of mica, behind which is a card bearing the name of `onecandidate. These names are inserted' from the back of xthe machine whenit is being prepared for-'an election, and after arranging the groupmechanlsm as deslred,

is prevented by lockingthe casing 1, until the closing of the polls. lIn this way the voters-control over the machine' is limited to thelegitimate use of key A and the writv ing on paper in box B, My votingmachine is mountedl on a Suitably constructed casing 1, arranged in abooth or like structure, and theentrance is guarded by an entrance-lever2 arranged at one end of the casing, and an exit-lever 3, located at theother end of the casing, the voter standin 'in front of the casing be#tween the sai levers when-voting. The enchine, as seen in Fig. 1; Fig. 9is a sectionalname can be written. The mechanism forall further accessto the rear of the machine trance-lever 2 is normally; ina lowermostfposition, an'dwhen the voter desiresto vote,

he raises the lever 2 which unlocksthe voting mechanism to permit votingand then steps in front oil' the casing, the lever 2 immediatelyswinging back to its normally horizontal position. rllhereafter thelever 2 may be raised at any time before lever 3 is rai.,cd withoutall'ecting the voting mechanism in any way. In .leaving the booth aftervoting, the voter raises the exit-lever 3 which resets the votingmechanism and sets the ent-rance lever 2 to. permit the entrance ofanother voter.- These levers 2 and 3 work alternately, and when one isset the other may be moved up and down freely without affecting thevoting mechanism, but when the set lever is operated, the other leveriin-- mediately thereby comes into engagement with. the votingmechanism, is set, and the operated lever is loose.

In order to accomplish the above results, I provide the followingdescribed mechanism, special reference being` made oFigs. 2, Il, 10 and11. r1`he entrance-lever is fulerumed at 5 in a suitable .support t5,secured to the. outside of the easing 1 and at its pivoted end is turnedto form a short arm 7, n

the end of w'hich is connected to a lockinghook 8 within the casing 1 bya link. S) which extends through a slot in thecasing 1. The locking-hook8, pivoted in a support 10, has its lower end provided with a tensionspring 11, for the purpose of retaining theloekinghook 8 in a lockedposition when possible. IVhen locked, the locking-hoolcS engages theupper face of a transversely extending arm 13, iixedly mounted on ztheshaft lat, which extends .longitudinally within the cas. ing 1. To theend of the arm 13 is attached a tension spring 15, secured at. its otherend to a bracket 16 on the casing 1, in such a manner that when thelocking-lmok is disengaged from the upper face of the arm 13, the spring15 contracts and 'draws vup the arm,thus turningl the shaft 141-.Vi'vl'ien the voter is about to enter the voting booth, he swings thelever 2 upwardly, thus drawing out the link E) and drawing thelockinghook S. from engagement with the aru113, which permits the spring15 to draw up tl arm 13, and turn the shaft 14- through an are of about90o.

Referringto Fig. 11 it will be. noticed by the dotted lines, that theupward motion of arm 13 is limited as shown, by reason of the fact thatfurther contraction of spring 15 must be on the axis passing through thecenter of shaft 14 and bracket 1b, or in other words, when arm 13reaches this dotted position, motion either vay is against the ac; tionof spring 15. In this way the shock due to a sudden stop is eliminated,and the life of the parts is prolonged. Raising the lever through anarc'of 30 is-sutiicient to release the arm 13 from the loek1ug-hook andaccomplish this' result. yThe balance of the movement of level' 2 has noeffect upon themachine. r1`he voter then passes in front of thevoting-booth and drops the lever 2 which immediately falls back to ahorizontal position. The swinging motion ofthe lever 2 is limited andfor this purpose the l-ever moves between two segments 18, 1S, and isrestricted by two pins 19,. 20, the upper piu 19 being placed in such aposition as to prcvent the lever-2 being raised to a vertical position,and thereby insure its return to a horizontal position. through theforce of gravity when released by the voter. In Fig. 11 it will benoticed that the lower or sector portion of arm 13 is adapted to holdhook S in its withdrawn position duringthe time that said arm is up;consequently, means must be provided whereby lever 2 can be loweredwhile hook 3 is thus withdrawn. This is accomplished by cutting a slotin the inner end of link 9, and is sluiwn in Fig. 2.

Then the voter is through voting, he swings the lever 3 upwardly andthereby 'auscs the shaft-21 upon which it is mounted, and which extendsthrough the casing and rotates in a standard '22, to turn.` Upon thcshaft 21 is fixed a cam 24 which engages an arm lixed upon thc shaft'l-t, and when the shaft. 21 is turned by the raising of the lever 3,the shaft 11 is also rotated through the medium of the cam 24 and thearm 2' in a direction opposite to the direction in which it was rotated.when it was released by the raising of the lever 2. As the shaft il isthus turned, the locking-hook 3 again engages the upper surface of thearm 13 and locks the shaft .ll in thatv position so that it cannot bereleased except by raising 'the lever The voter then passes out and thelcvcr 3 drops back to a horizontal position. The machine is thenprepared for the next votc. The swinging motion of the lever 3 islimited by a guideway 28 in which it moves, the ends of' which formstops for the lever in a similar manner as in the case of lever 2. Theguideway 23 is preferably formed in casing 2t).

Referring to Fig. 10 it will be .seen that cam 211 impinges against arm25 during the entire time of swinging of lever 3, and furnishes a lockwhich prevents lever 2 from operating the voting parts while lever 3 isup. This is advisable to prevent premature raising` of levcn2 fromlocking arm 25 behind cam 2l, in which case the machine would have to beopened and the parts repla-ced. I prefer to provide levers 2 and 3 withlocks 2a and 3LL for use ivlieirthe luachine is not in service.

On the shaft 14, are secured aplurality of transversely extending 4arms30, for controlling, locking, unlocking and setting the voting devicesarranged inthe easing 1 and` actuated by= the voter using a- .key on akey- 4spi-tulle :40, extending transversely, and

mounted to turn in lsuitable bearings arranged in the frontofthecasing 1. key-spindles 40 are arranged in vertical rows, shown inFig-1, and on the casing l at thetop of each row is a legend 41 indi-Veating straight tickets, oflices of candidates -tofbe voted for,licenses, schools, etc., the

ing the corresponding key-spindle in the dles in the whole casing becomelocked and hence the .voter cannot turn' any other keyspindle in thecasing.

Incase the voter does not vote a straight ticket, he can turn' in eachrow, following vertically, as' many key-spindles as there'arepersons-'to bepelected for the corresponding offices-that is, forinstance,A for mayor, a single voter, can only turnone of thekeyspindles 40, as only one mayor is to be voted for. In case threemembers of the school com` The three'rows marked School are pro- 'videdwith ke -spindles 50, having a different key slot or the use of aldifferent key in the hands of a female voter, so that a' fem-ale votercan vote under schoot but cannot use the key 1n any other row.

. .Referring to Fig. 13 it will be noticed Y that key` A is providedwitha c entral recess cz, and two projecting lugs al, al.- Keyspindle 40is provided at its forward end Awith a reduced portion adapted to titrecess o, and near its forward end with two slots I, b1., formed toreceive lugs at, a2. Lugs el, a2, upass through two slots c1, 62, in thecasing 1,when t-he key A is inserted, and the key cannot be turned untilthe lugs have passed entirely within the casing 1 and cn-l teredrecesses b1, b2.. Likewise the key cannot be withdrawn after operatingthe spindle 40, until a half turn has been given to said s )indle,although, as willbe hereinafter descri d, should the voter wish tocancel any vote he makes, he has but to bring key A backto its originalposition, when it can be readily withdrawn.

Female voters are provided with a key 4`similar to that. alreadydescribed, but having in addition two auxiliary lugs r1.3 and' et,

y (see dotted lines i'n llig. 13,) adapted to pass through openings dand (l1, which are provided only.for spindles where candidates are to beballoted for by females.

To insure register between recesses 7;, lIN, and slots nl, 2, ,l providea mechanism on the rear of spindle 4() which is illustrated in Thisconsists of two spring pressed pawls 31, 31, pivoted to the back' plate34- at 32,'and i'iornmlly held by springs 33,33', in engagement withrecesses m spindle 40. These recesses are cut d1- reetly opposite eachother so that a half revolution of spindle' 40 will cause each pawl 31to rest in the previously opposite recess.

()n each key-spindle 40 and 50, is secured a wheel 42, within the casingl, and the said wheel 42 is provided with two diametrically disposedteeth for meshing with the corresponding teeth on a rack 44, mounted toslide up and down in the casing, and on the lower end of each rack 44,is secured a laterally extending foot 45, adapted to be ,engaged on itstop by a corresponding cross arm 30, on the shaft 14, and the free endof the said foot- 45 refs-ts on the foot piece 46 of the slide 47,disposed vertically on the other side of the key-spindle 40 in each row.Now when the cross bar 30 ofthe shaft 14 rests on the foot 45, then theshaft 14 is locked, and neither the rack 44 nor'the slide 47 can beraised; when, however, the shaft 14 has been turned, on swinging thelever 2 upwardly, then the cross arm 30 swings u ward and releases thesupporting feet 45 of all the voting devices, to allow the'voter to turna 'key-spindle -40 or 50 half way around, for the corresponding tootho-f the wheel 42 to lift therack 44.

On each key-spindle 40 is secured a cam wheel 48, having twodiametrically disposed teeth adaptedI to be engaged by a dog 49,pivotally mounted at 52 in the casing 1, the lower part of said dog 49being weighted so as to normally h old it against a stop pin 51, incasing l and away from the lower tooth of wheel 48. The function ofthese teeth in wheel 48 is two fold, viz.- first, to raise forked lever56 when spindle 4() is rotated in voting direction, and second, topresent abutting surfaces alternately to dog 49 and arm 58 of lever 56,thus preventing, at proper times, forward or rearward rotation ofspindle 40. Likewise, when lever 56 is up, a counter rotation of spindle40, (which is possible only atsuch times) will cause the then uppertooth of wheel 48 to move lever 56 down around its pivot 57 in casing 1."Wheels 42 and 48 are of said dog with the teeth of wheel 48.

67 is'an indicating lever pivoted to casing 1 at 68, and mounted betweensaid casing and thecard upon which thename of the candidate is written.(See Figs. 2, 5, 7 and 8.) The forward end oflever 67 is adapted to beoperated by lever 56, through the agency of a pin 66 working through aslot 69 in casing 1, so as; toipresent. alternately the contrasting faceportions `70Aand 71 on the free end of lever 67 to the opening 72 in thecard. The lower face portion 70 'distance ofone tooth on rack 44.

preferably white and the upper face portion 7l, is preferably red; (seeFig. 8) so that when the spindle is ready to be voted, as in F ig. 7,the lower orwhite portion 70 is presented to opening 72, but when thespindle is Voted, as at X in Fig. 2, the upper portion 7l is presentedto opening` 72. A voter can thus keep himself informed as to thespindles he has operated.

In Fig. 2, spindles X and Y have been voted, as has been one of thoseinvertical `row Z. It will be noticed that 'in row Z,

feet 45 and 46 have gone up together for a In the vertical rowcontaining spindles X and Y, foot 45 has ascended for the spaces of twoteeth, leaving foot 45 at the same position as in row Z. 'lhis featureis a characteristic of group Voting, which is more fully describedhereinafter.

For the purpose of arranging the voting device in each vertical row topermit voting for one or more candidates in that row, I provide thefollowing mechanism.

The lower portion of each rack 44 is vprovided with a rib 75, upon whichis held, in slidingengagement, a collar 7G, adapted to be fastened 'inany desired location on said y rib by. a set-screw 77, whiehcollar 76 isadapted to abut against the under side of a bracket 78, through whichthe rack 44 and the' slide 47 are free to move. l/Vhen but one candidateina Vertical row is t-o be voted for, then the collar 76 of theparticular rack 44 is set at such a distance from the bracket 78, thatwhen the rack 44 is raised by the voter giving a half turn totliekeyspindle 40, then the collar 76 abuts against the bracket 78, andthe rack 44 cannot be raised up any further, which prevents any of theother key-spindles in that particular row lbeing turned. If twocandida-tes for one oiiice or in a vertical column are to be voted for,then the collar 7 6 is set twice the distance from the bracket 78,andtwo key-spindles can be turned and t-he rack 44 raised two steps'before the collar 7G prevents further voting by abutting against thebracket 78.

When the racks 44 are in the lowermost or normal position or after thekey-spindle has been turned, the teeth of the wheel 42 are out of meshwith the teeth of the rack, and when the key-spindle is turned by thekey for the purpose of voting, one ofthe teeth on the wheel 42 engagesthe teeth of the rack 44, and lifts it a certain space bcfore it isturned out of mesh; but it will be noticed that in turning one spindlein a vertical row, thereby operating the rack 44 as described, said rackin movmg upwardly does not engage any of the other Wheels 42 in'thatrow. This is clearly seen by an inspection of Fig. 7. It is thereforenecesteeth adjacent to each spindle 40, so that there will alwaysA be atooth of said rack ready to be engaged by any of the wheels 42. Thefirst spindle voted will carry the upper tooth of each series by itscorresponding wheel 42, and the second-spindle will cause operation on'the second tooth, etc. Likewise in resetting the machine, rack 44 willreturn to its lowest position without affecting any of the spindles,`those voted being reset by slide 47 through the action of its pin G4 onend 63 of lever 5G. ln this manner, all the voted spindles are resetsimultaneously.

When a voter desires to change a vote he has already made, he has but toreverse the motion of key A, and the parts are thus put back in theirformer positions. The method of aecomplishing` this will behestunderstood by an inspection of Fig. 7 and spindles X and Y of Fig. 2.

As before mentioned, l `ig. 7 shows the paris ready for voting. Byturning spindle 40 in the direction indicated by the arrow, the lowertooth of wheel 4S engages cam surface 4l"L on lever 5G, and raises saidlever to the positions shown in X and Y. The raising of lever 5G bringsfoot 58 into the path of the lower tooth of wheel 48, and prevents morethan one half a revolution of said spindle 40. Lever 56 also raisesslide 47 through its pin G4, as before described, and actslto releasedog 49, which revolves by gravityuntil it is in the position shown at Xand Y. It is then possible to reverse the direction of rota-tion ofspindle 40 for half a turn, the upper tooth of wheel 4S impinglingagainst foot 58 and throwing it out to its first position, and bringingend G3 of lever 5G against the head of dog 49 and throwing the lower endof said dog into position to stop the backward rotation of spindie 40. Iprefer to provide friclional means at pivot 57 for maintaining lever 56in its raised position1 although it is obvious that. the same resultswould be obtained by the use of a spring. llvhen a voter leaves thebooth, he sinmltaneously and automatically resets all spindles voted, bymeans of pins 64, as vbefore described.

ln order to prevent the racks 44 fronrbcing propelled too far. and alsoto hold them in position, a brake device is provided` consisting of abrake-lock 80, hung on a pivot 8l. supported from the casing. and thefree end of the said lnalw-block is pressed in by spring 82 to hold thelnake-block in fric tional engagement with the rack. Then- `ever therack 44 is raised by the turning of the key-spindle 40 and the wheel 42,the above` brake device retains the yrack 44 in the raised positionafter the wheel 42 has passed out of, mesh with the teeth in the rack,land the rack is successively raised by the revo lutions of the Wheel 42.The slides 47 are raised but one distance, no matter how manykey-spindles are turned in one row, and when the rack 44 is presseddownwardly into the-lowermost osltion by the arm 30, then the foot 45ci) the rack engages the foot 4 6 ofthe slide 47 and also draws thisslide back into a lowermost position.4

A44 and slides 47 respectively. Thus when the 4voter turns one ofthekeylspindles in the straight-ticket-voting device, then the upwardmovement of the rack44 imparts a swinging motion to the bell-crank lever86, so that the slide 87is shifted longitudinally to bring theshoulders-88 and 89 in register with the corresponding -tongues 90 and91, to lock all there'maining racks 44 and slides 47 of theothervotingdevices to prevent the voter turning an of the otherkey-spindles.

When the mac ine is reset by the turning of the shaft' 14 as heretoforeexplained, then the downward movement of the rack 44 for thestraight-ticket-voting device imparts. a return swinging motion to Athebell-crank lever 86 to move thelocking slide 871out of locking positionrelative to the tongues 90 and 91. f. y

It is of especial importance that a voting machine rmitwhat may becalled, group voting, ot erwise the voter is restricted 1n his choice ofcandidates in certain cases, and prevented from voting lfor'certaincombinations,

of candidates. For instance to illustrate, suppose four aldermen aretobe elected, the voter .has the right to vote for any four alf.dermaniccandidates irrespective of party.'

But as the candidates ofeach party are in horizontal. rows, the list ofvaldermanic candidates of all 'the parties would occupy four y verticalrows. in the machine, as shown in .Fig 1; therefore, if Vthe votingmechanism is set to permit of but one candidate being voted for ineachvertical row,the voter is restricted in his choice, andcannot vote fortwo aldermanic candidates of different par# ties, Vif they happen tofall in the same ver tical column. In order to obviate this dis-1advantage and to permit a voter to vote -for' any four candidates in thefour vertical rows, 'and for not more than four, 1 provide thefollowing'device which locks the four aldermanic rows, when any fourkey-spindles have been turned, whether they are all in lone `verticalrow or one horizontal row Aor scattered in the 'differentv vertical andhori- .zontal,rows. fEach rack 44'ofth'e groupiis provided in its lowerportion with a series of teeth 100, which engage -star wheelsl 102rigidly mounted on pins 103, set in the casing 1. Adjacent to star wheel102 and also rigidly mounted on pin 103,'is a pinion 101 engaging ahorizontal rack 105, which is free to slide in brackets 106, secured tothe casing. Star wheel 102 is here shown with exactly half thenumber ofteeth that is c ontained by pinion 101. It is essential that all ofthese pinions 101 shall be alike, so that the action 'of any one upon,rack 105 will cause exactly the same displacement of all the' starwheels, thus insuring the proper presenting lof fa tooth in said starwheel to the teeth 100 of rack44. It will be noticed that the pitch ofteeth 100 is such that an impulse presented to one star wheel 102, byone rack 44, will4 permit theother star wheels to revolve freely withoutafecting their respective racks. ment of anyrack 44 will give rack 105 adefinite movement to the right. (See Fig. 2.) The two brackets 106 atthe left end of rack 105 act as sto s for a block 108 mounted on saidrack and imit the movement to, in this case, four votes. Collars 76 arenot used unless there is to be a partial restriction in choice, as forinstance, when there are but two parties in the field. When rack 105 hasbeen moved for four votes, and is against the right hand stop 106, itis. necessary that the resetting of the machine by lever 3 shall alsoreturn rack 105 to itsv original positionagainst the left hand .stop10.6. To accomlish this, I mount a vertical rack 110 in brackets 111,V so asto be engaged by a pinion 113 whose face is wide enough to alsoengage rack 105.

The lower end ,of rack 110 is provided with a foot 112 positioned to beengaged by anv Thus, veach upward movearm 11,4 bn shaft 14 in a mannersimilar to that of arms 30 on feet 45. Lever` 3 operates tobring rackdown, (it has of course, ascended with each movement of rack 105) andthis movement will impartlv reverse motionto pinion 113 andthus-moverack 105 to its start-ing position.

t The mechanism-for registeringthe num-A ber of voters using themachine, is lllustra'ted in Figs. 2 and 17, and consistsl of a verticalrack 35 engaging a pinion 36 mounted on a stud 37, which carries asuitable registering dial 53. (Fig. 17.) Rack 35 is normally maintainedin its upper positionby spring- 38, and has a foot 39 adapted to beengage by arm 43 in a manner similar to that of arms 30. When lever 3 israised, arm 43 impinges against foot' 39, andvmescs. rack 35 downward,operates pinion 36 andcauses vone advance in the registeringdeyice 53 onstud 37. Thisregistermg device will preferably be provided withalrordinary ratchet and pawl'. arrangement 54, to revent retrogressionof the registering dev1ce during the upward motion of rack 35.

isp

its underlying principle, the well known metfr-registering device.consisting oi three countingl dials 't. --l, ft, arranged upon spindlesl2, l2, l2, and adapted to cooperate in a manner to be described.

The units dial carries upon its spindle 12 a gear 17 which is in meshwith pinion 23' upolispindle 40. vOf the two inclosing plates 2&1, 26,between which the registeringl device is lnountcd, the rear one has'suitable openings 27 which expose the proper numbers on dials at, el,l.

The 'foregoing is oi old and .well known construction.

It is essential to the successful operation of my registering device,that the dials can be counted either backward or forward with equalfacility, and it is also important to have careful register ot thepropernumbers opposite openings 27. 4

l iind in practico that the ordinary intermittent gears will not givesnliicient locking surface vto prevent slight movements ot the dials,which, while not in any way conducive to defective register, is likelyto cause errors in taking the readings, as the numbers are not alwaysfully exposed. To overcome this defect, I construct my intermittentgears in the following manner.

The locking disk (30, and count-ing tooth (3l, are made in separatepieces, both rigidly locked with gear 17 on the units spindie 1Q. On thetens spindle 1Q is mounted a serrated disk G2, which is positioned to belocked by disk G0, and an operating disk G5 positioned to be operated bytooth (il. Disk 62 has for its circumference a series of ten arcs,having the same radius as disk 60, and.

disk G0 is provided with a notch (30a for receiving the points made inthe circumference ot disk 62, by the meeting of these ten arcs. Disk 65is provided with a series of ten recesses 65a, each adapted to receivetooth 61. The operation is the saine as in the ordinary intermittentgear-,but by making the com bination of four parts instead -of two, Ieliminate the necessity of shortening of length of the ten arcs on thecircumference of disk G2, which would occur were the recesses (55a cutat their n'iceting points, instead of beneath them, and thus secure abetter lock on dials 4. 'The tens spindle Vl2 'is also provided with alocking disk O0 and counting tooth (3l, which engages a similarserrateddisk (32 and operating disk Q5 on the hundreds spindle.

Vhat I claim is l.
